Practical information on particular test methods
Regarding test equipment and the related auxiliaries, EDANA advises as follows:
- A small part of the test methods require customized parts that are only available on demand. Guidance to suppliers for those parts can be found in the below table.
- For most NWSP test methods, there are multiple commercial companies that offer equipment designed for those tests. These companies can easily be found on the internet.
- For some equipment, for methods not widely used, you may find helpful information in below page. Please note that EDANA provides that information as a service without endorsing any of the suppliers or guaranteeing availability.
